This invention relates to tell-tale wear plates and more particularly to a removable wear 'pl ate for protecting the walls of casings such as oil. and gas separators and 1, the like from abrasion and wear incidental to impacts, friction or tangentialidischarge of fluids carrvinr 11 abrasive material such as sandandthe like. 1 1 1 1 g V 1 Another important object of the 1nvent1on 1.1 is to provide tell-tale means for indicating exteriorly off the casing when the wear plates areabout worn through so that they may be replacedbeifore the sidewalls ofthe casing are exposed to the abrading 313M011.

l5. It is also an ob ect of the invention to provide the wear plate in sections so that they may beyinserted through manholes or other openings inithe casing and so that individual; sections -may be replaced when 112;? they become Worn without replacing the entireplate. y 1 1 1 1 1 In accomplishing these and other ob ects of the invention, I have-provided improved details of structure, the preferred11 form of 11 which is illustrated in theaccompanymg drawing, whereinz; 1 1 11 1 Fig.1 is awsectional V1ew thro11gh aportion of' a, separator illustratlng a sectional wear plate embodying my; 1nvent1on.- 1 1 1:11 1 Fig. 2:1is a; horizontal sectional view 1011 Fig. 3 is a detailsectional view through a circumferentiallv against the inner; faceof the wall The fluid is discharged through i the inlet pipe at high pressures and often one i 1 ing openings 11 in the wall of the sepamodate nuts 14to clamp carries large quantities of sand and similar abrasive materials which Quickly wear away the walls of the separator at the points of impact so that it must be replaced with a new one while the other parts thereof are in 0 good working order. 1

To protect the wall of the separator I 1 have [provided an arcuatespaced wear member 3 which is attachedto and supportedby the wall 1 to receive; the impactfof the fluid and which may be formed from a material having greater 1 wear resisting properties than the wall of the separator. 1 g 1 1 The member 3 is preferably formed of a plurality of plate sections 4, each ofwhich has its forward edge flanged outwardly to-1 ward the wallof thetank as at 5 to slightly underlapQthe rearedge 6 of the adjacent section. The sections are preferably wider at their rear ends and the forward edge of 6 each section is of the same width as the rear edge of the preceding section to provide gradually increasing width for the wear plate-as the fluid stream spreads in impacting against the sections.

In order that the condensate and spray collectingon the walls ofthe tank above the wear plate may drain to the bottom of the separator, the wear plate sections are spaced from the walls by spacing blocks 7 7 to provide a channel 8 therebetween.

The sections are preferably secured adjacent their corners by fastening devices such as countersunk head bolts 9, which act as tell-tale members, extending through open- 1 ings 10 in the sections and through alignrator, the heads being countersunk in the sections to lie flush with the inner "faces thereof as shown at 12 in Fig. 3. The threaded shanks 13.01? the bolts extend beyond the wall of the separator to accomthe sections to the wall. 1 1 1 i 1 The' bolts also preferab y extend through openings 15 in the spacing blocks to retain them in position. However, the blocks may be welded or otherwise supported by the sections.

Suitable gaskets or washers 16 and 17 are inserted between the spacing blocks and the wall of the separator and under the nuts 14 for sealing the openings about the bolts to provide gas and liquid tight joints.

In order to give warning when the plates have become worn to such an extent that they must be replaced to protect the walls of the separator, each bolt is provided-with a channel 18 which is drilled longitudinally through the shank to a point slightly beyond the outer face of the sections as shown in Fig. 3.

It is thus apparent that the forces wearing away the sections will also wear away the bolt heads to expose the inner end of the channel, whereupon an oil spray will be discharged therethrough to the exterlor of the separator, causing the bolt to act asatell-tale member and'give warning that the plate sections must be replaced.

It is essential that the wearingquality of the plate and bolts be substantially the same so that the wearing away of both will be equal.

It is obvious that the tell-tale member may be cast integral with the wear plate and project beyond one face of the plate, and that in such construction the tell-tale member will be provided with alongitudinal bore or channel terminating at the wear limit of the plate and extending through the wall of the casing. The integrally formed tell-tale'member may also be used as a securing means for the plate by threading the same for a nut or by welding it to the casing.

My tell-tale plate may be also used as a lining in hammer mills, coal crushers, and various other places and in event only solids are handled, there will always be small particles present which will find their way through the channel in the tell -taleimember when the danger point has beenreached to serve as a warning.

What I. claim and desire to secure by Letters Patent is: I

1. In combination with a tank having a fluid inlet, a wear plate associated with the inlet to receive impact of fluid discharged through the inlet, means for spacing the plate from awall of the tank, and fastening means for the plate extending through the wall of thetank and having means for indicating wear on said plate.

2. In combination with a casing having an inlet, a wear plate comprising sections associated with the inlet to receive impact.

of material discharged from the inlet, means for spacing the sections from a wall.

a of the tank, and means extending through said spacing means for indicating wear of the sections caused by abrading action of the material.

3. In combination with a tank having a fluid inlet, a wear plate secured to a wall of the tank and associated with the inlet to receive impact of fluid discharged through the inlet, means spacing the wear plate from the wall of the tank, and means extending through said spacing means -tor indicating wear on the plate caused by abrading action of the fluid.

4. In combination with a tank having a fluid inlet, a wear plate associated with the inlet for receiving impact of fluid discharged through said inlet, fastening means for supporting the plate having a channel for emitting a spray of the fluid exteriorly of the tank upon wear of the plate.

5. In combination with a tank having a fluid inlet and having openings therein, a Wear-plate associated with the inlet to receive impact of fluid discharged through the inlet and having openings aligning with the openings in the tank, bolts extending through the openings for securing the Wear plates to the tank, and having channels for emitting a spray of fluid upon wear of the plate.

6. In combination with the wall of a tank having a fluid inlet and having openings therein, a wear plate associated with the inlet to receive impact of fluid discharged through the inlet, and having openings aligning with the openings in the tank wall, bolts extending through the openings for securing-the wear plate, having means for indicating wear on said plate, and means on the bolts for spacing the wear plate from the wall of the tank.

7 In combination with a tank wall having a fluid inlet, a Wear plate associated with the inlet for receiving impact of fluid discharged through said inlet, bolts for supporting the plate to the tank having means for emitting a spray of the fluid exteriorly of the tank upon wear of'the plate, and spacing means on the bolts forspacing the plate from the tank wall. I

8. A wear plate for oil and gas separators comprising the combination with a tank having a tangential fluid inlet of a plate located on the inside of said tank and so situated as to receive the impact of fluid entering through said inlet, and means having longitudinally extending channels therein for securing said plate in position, said securing means being of a material having substantially the same wearing qualities as the plate, whereby said channel will be opened and a spray of fluid pass through said securing means when the plate is nearly worn through.

9. A wear plate composed of a plurality of adjacent sections of gradually increasminating adjacent said head whereby said ing width, bolts having substantially the same wearing qualities as said sections for securing the sections in position so as to be subjected to wearing action, and longitudinal channels formed in said bolts, said channels being of such length as to be,
